set cornerRadius and setbackgroundimage to UIButton

Question

Here is how I would create a button through code and set its background color.

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(100, 100, 100,50);
[btn setTitle:@"Hello" forState:UIControlStateNormal];
[btn setBackgroundColor:[UIColor colorWithRed:128.0/255.0f green:0.0/255.0f  blue:0.0/255.0f alpha:0.7]];
btn.frame = CGRectMake(100.0, 100.0, 120.0, 50.0);//width and height should be same  value
btn.clipsToBounds = YES;

btn.layer.cornerRadius = 20;//half of the width
btn.layer.borderColor=[UIColor redColor].CGColor;
btn.layer.borderWidth=2.0f;

[self.view addSubview:btn];

Below is the image of the button that is related with the above code

You can always play around with code and create the colors that you need for background and border. Hope this would help you out.

btn.clipsToBounds = YES; 

i Just added this and it worked for me. I was actually able to set corner radius to UIButton with setting an image to that particular UIButton.

You can also have:

btn.clipsToBounds = true;

If you are using the image in your button background then you need to set clipsTobounds to true.

button.layer.cornerRadius = 10 
button.clipsToBounds = true
